I stayed at Ventura for three nights and it was absolutely lovely. The staff here are super friendly, helpful and such a pleasure to deal with. The hostel itself is clean and the rooms are exactly what they look like in the pictures. I really enjoyed my stay here and when I return to Madrid, I will definitely book in with them again.
And for the previous guest who mentioned the loud noise every night, that's why ear plugs were invented, I brought mine along and slept like a baby each night!!
